Application mea August 17, 1912. serial N;71'5,563.

To all whom it may concern Be it known that I, HENRY W.V ODown, acitizen of the United States, and a resident of Jersey City, county ofHudson, and State of New Jersey, have made certain new and usefulImprovements in Sad-Irons, of which the following is a specification.

The vinvention relates to sad irons, and more particularly to that kindof sad iron which is heated by a gas burner contained in the iron. e

Objects of theinvention are to provide an improved device of thecharacter referred to which', while simple and durable in construction,shall be highly eflicient and eco'- nomical and safe in operation.- Y

These and other objects of thei invention will in part be obvious vandin part more fully explained in the follovvingl description, f

Theinvention consists in the novel parts, improvements, combinations,lfeatlires of construction herein shown and` described lIn theaccompanying drawings, which are referredto herein and form a' parthereof, is illustrated an embodiment of the invention, the same servinginconnection with the description hereiny to illustrate thepri'r'lci-4ples of the invention. n

Of the drawings: Figure l is a perspective view of an embodiment oftheinvention; Fig. 2 is a vertical central section of the same, partsbeingshown in perspective,t Fig. 3 isa perspective view of a detail; andFig.

A sad iron constructed-.in accordance Withcertain features ofthemventIoncom'prI-ses" in combination, a casing forming a chamber, a basehaving transverse'corrugations', a plurality of said corrugations beinghollow to form air passages and having openings" in theirV upperportions to admit the air to said chamber, anda burner arrangedlongitudinally in said chamber and above said corrugations, saidlburner. having perforations arranged therein to directfthel flamedownwardbetween said corrugationsrf According to-other features of theinvention, a plate Vis arranged at the bottom of said chamber and saidplate iscorrugated, the yplate being castI with the' ridges* of thecorrugations' hollow as` above set forth; the

sides and rear wall of theA casing'are formed with openings thereinfor'thevescape of the heated products of combustion, said open-,

ings being' of sufiicient capacity to set up a circulation; a hinged topis provided for the iron,V and an air-mixing tube is provided for the'burner.

VReferring now tothe drawings in detail, the embodiment of the inventionillustrated comprises a casing 6 ofthe usual configurai tion andformingV achamber 7. Into this chamber is introduced through anorifice'8 in the rear wall o'f the casinga burner A9 ofl the Bunsentype, the air mixing tube 10 of which is arranged outsideof thecasingand isl connected in la vusual manner 'with ther i p While theburner 9 may be arranged in the said chamflexiblev gas tube,4 not shown.

ber in a variety of .ways,preferably and as shown, itextendslongitudinally and cen trally ina horizontal' plane of thechamber,

bei-ng held in placefforward by a piece 12 fitting into acorrespondinglyshaped recess in the front of the casing. The burner issupported also on lugs 13 and 14 of suitable height andsituated,respectively, at-the opposite ends ofthe chamber?, and to these lugssome further allusion will be 1made.-

4As shown, the burner V'Z' and mixing tube 10 are ljoined byafla'ngevl', suitably ree' cessed for that-purpose, said'ilange beingsuitably secured,vas by screw 17, at its top to the rear wall of thecasing. 'Io` prevent y the heatingof the vmining tube 11,0 by the burner9, preferably a gasket 18.0f suitableV i 1 insulatingmateriahfasasbestos, is disposedv between the rear "wall" ofthe casingand ythe flange 16. In order that the base of the said' ironi may be'heated to the best-advantage, the burner" 9', vpreferably and las shown,is formed with a plurality of perforations 19 in its under side,- towhich further refer-v ence-.Will presently be made.

Means are providedy for supplying air to the burner 9 tomaintaincombustion. This means comprises a plurality of air passagesformed in` thebase ofV the" casing and ary ranged transversely vof thechamber 7 at suitableintervals and having` openingsvso A disposed'fas tosupply at points adj acentvto i the perforations 19.- of the burneratmosv ph'eric airfconducted' through said passages;

WhileV these air'passages may be provided" in variousways,rp.referably^and asfshown, a

plate 20 conformingin outline tothe walls of the chamber 7 placedin' thebottom of said chamber, thesaid-lugs'l and; 14 which are formed on saidplate serving not only as supports for the burner 9 but also to keepsaid plate in position. As shown, also, said plate 2O is corrugatedtransversely to form alternate turrows 22 and ridges, which latter arecast hollow to form the air passages 21, openings 23 being formedin theside walls of the casing G in register with the air passages 2l. Theridges also 'have suitable openings 25 in the center thereof, throughwhich the atmospheric air enters the chamber 7. The perforations 19hereinbefore referred to are so disposed on the under side of the burner9 that their liames are directed into the furrows Q2 and the heat isthus imparted quickly and without waste to the bottom of the iron.

Suitable vents for the waste products of combustion are provided, thesame, preferably and as shown, consisting of openings 27 formed in theupper side and rear Walls of the casing 6. 1t is to be noted that theseopenings are of sufficient extent to afford -a capacity equal to thekdemands of the burner with its primary and secondary air supplies andthus maintain a proper circulation.

The casing is provided with a hinged top 29 which is suitably secured tothe casing, as by means of hinges 30 and the thumb screw 32 whichoperates in registering openings in the top and casing and whichprojects inwardly over the said top, as shown in Fig. 2, and this holdssaid top in position. As also shown, a handle 33 is removably secured tothe top 29, as by thumb screw 35, which operates in suitable recesses inthe handleJ and top, lugs 36 and 37 being also provided on thehandlevwhich tit in suitable recesses in the top 29 and thus'steady thehandle.

1t will be seen that a sad iron constructed in accordance with theinvention will carry out the objects of the invention, as heretofore setforth, and will possess other advantages which will be apparent to thoseskilled in the art.

The invention in its broader aspects is not limited to the preciseconstruction shown and described, as many changes may be) made in thedetails thereoll without departing from the main principles of theinvention or sacrificing its chief advantages.
